This paper presents a novel RF rectifier that compresses RF input impedance fluctuation caused by DC load change for reducing return loss at RF input power. The proposed rectifier connects twin basic RF rectifiers and a quarter-wave impedance transformer. The proposed rectifier automatically switches the two rectifiers according to DC load resistance.

We propose a novel, extremely simple rectifier whose input impedance is insensitive to the variation of the load resistance. Thanks to this insensitivity, the reflection loss caused by the load variation is minimized, and thus the rectifier keeps high efficiency in a wide load range. This characteristic is welcomed by wireless power transfer, especially for(More)
